Abstract: The present invention relates to a method of directly preparing a dicarbamate compound from a diamine compound, and more particularly to a method of directly preparing a dicarbamate compound by reacting a diamine compound with an alcohol compound in the presence of a mixed gas of carbon monoxide (CO) and oxygen (O2) using a Pd/MOx catalyst configured such that a palladium (Pd) active metal is supported on a metal oxide or metalloid oxide carrier.

Abstract: The present invention relates to a Ru—Pd bimetallic catalyst for use in hydrogenation of a compound, and more particularly to a catalyst prepared by loading both ruthenium and palladium on a g-C3N4 support and to a selective hydrogenation process of a pyridine group in a reaction system containing both a pyridine group and a benzene group using the catalyst.
